This plate is a common and elegant ornament of shrub- 
beries in this country, flowering profusely from August to 
October, when little else is in bloom. Its frequently met

which will define with precision the limits of the genera. 
Whether this arises from a’ want of terms to express ‘ideas, or 
from deficiency of discriminative perceptions, or from: all 
genera being mere artificial groups, combined by naturalists 
Jor purposes of convenience, ‘and not existing in nature, are 
questions upon which it is not necessary to enter in this 
place. But whatever may be the cause, the effect is certain, 
and experienced in no tribe of plants more sensibly than 
among the European genera of Leguminosze, to no one of
